That was good
There are a few things that you should probably try to change up a little bit.
The platform thing should have really been noted much earlier in the game. Because you stressed that part of the originality of the game is the ability to choose where you can respawn, you should have just introduced that at the beginning, instead of introducing the more obvious things that you can do in the game, or make a tutorial level that introduces the use of the respawn platform more. It is a unique idea, and I don't think you sold it very well.
The controls are another thing, but you admitted to them, so no big deal.
